Well, it's claimed that the knowledge died with Kun, not Nadd, in JATM. So Kun probably did have access to that knowledge. As for how quickly he studied it, no idea.
The Fact File quote is this:
The TCSWE quote is this one (retconned to be "once the most powerful", so that Palpatine could remain supreme):
Nadd was only 400+ years before Kun. And he's a DLotS as well. How does that affect the Fact File quote anyway? Nadd was on the same page that Kun was proclaimed to be the most powerful.
I feel as though the TCSWE quote refers to all Dark Lords up to Kun's time, since it's plural. It doesn't make sense for it to be referring to, you know, himself.
Well, the Fact File quote refers to all Sith Lords, not just Dark Lords.
Are you referring to this quote, btw?
If so, then Nadd did claim a kingdom, so he'd satisfy the quote above, which kind of suggests that he was already a Dark Lord but needed to "validate" that by getting a kingdom, which, of course, he did.
The contradicting sources also claim that Nadd killed Sadow, or that since there could only be one DLOTS, Nadd left Yavin and went to Onderon. I just don't think Nadd was canonically a DLOTS.
But if nadd killed sadow, why did his spirit magically turn up a few centuries later? You can see my confusion since Nadd was trained by sadow's spirit, not his physical body.
Because he killed Sadow physically, and Sadow's spirit came back?
It's always been a mess, but TOR's disregard for continuity made things worse by bringing in Sadow's spirit again for no reason. They ended up just saying that Nadd destroyed Sadow in a codex entry, to avoid confusion, I suppose.
And no, later sources like RoT have Sadow surviving the six centuries physically, and TOR has Sadow placing his body in Stasis until Nadd came along. So Nadd killed him physically, and then Sadow's spirit gets wrecked later.
No no, i know sadow placed himself in stasis but all the sources I remember state that it was his spirit training Nadd, unless I'm wrong. Again, the same sources said Nadd didn't kill Sadow.
Nah, every source either says Nadd destroyed Sadow or just leaves it ambiguous. Not that he actually refused to destroy Sadow. But we should be taking the newest sources, which do state that Nadd destroyed Sadow.
Regardless, Nadd's a Dark Lord, per my quote above. Kun's more powerful than him
Yea, I've been checking swtor and they've retconned a lot of things. Oh well, my points still stand. The argument for Nadd is convincing in my opinion but the quotes, if interpreted a certain way, put me on the losing end.
"It seems they lost their powers when the scepter was destroyed."
So basically, simply by existing in the galaxy, the specter of Ragnos could grant hundreds of people (possibly non-Force sensitives) abilities like Force Lightning and Force Drain. The scepter would obviously just be a fraction of the power a living Marka Ragnos would wield.
